Application filed May-20, 1907. Serial No. 374,565.

To all whom it may concern:

Be it known that I, lVinnnn'r Gr. WISE, a citizen of the United Statesof America, and a resident of Akron, in the county of Summit and Stateof Ohio, have invented certain new and useful Improvements in VVater-Heating Appliances, of which the following is a specification.

My invention relates to improvements in water heating apparatus, andmore particularly" to such apparatus designed for the heating ofbuildings and employing gas as a fuel.

The object of my invention has been the production of an appliance ofthis character which shall be economical in operation, both as to thecost of attendance and fuel, simple and cheap in construction, and onewhich provides a'large heating surface and impedes the flow of the Waterthrough the heater as little as possible.

The furnace of my invention, preferably is constructed in verticalsections, each of i which is provided with its own gas burner,

-. invention.

and associated therewith'is an upper section wherein the water isfinally heated before passing tothe connected system of piping. Theparticular details of my improved construction, however, may be morereadily gathered by first making reference to the accompanying sheet ofdrawings, wherein l igure I is a perspective view illustrating a waterheating appliance embodying my Fig. II is a vertical sectional 'ViQLRthrough the same. Fig. III is a -hori- 'Aontal section on line IIIIIIindicated in Fig. II. Fig. IV is a side elevation of one of the verticalsections; and Fig. V is a per-' spective view of the upper reservoirprovided in the horizontal section of the heater.

Throughout the several figures of the drawings, I have employed. thesame character of reference to indicate similar parts, in order to avoidpossible confusion.

A seven-section heater is illustrated in Fig. I, and I may state thatpreferably the vertical sections are provided in odd numbers for thepurpose of more economically operating the furnace under ordinaryconditions. It is possible, of course, to employ any desired number ofsections. Each of the vertical sections a is provided with itsindividual lower and upper manifolds or sub-reservoirs a. M, which areconnected with those ofthe adjacent sections by means of the well knownpush-nipple. Serpentine ribs or flanges a? are provided upon either sideof the sections, which intermesh with those of the adjacent sections, asbestshown in Fig. III, to form passages for the heatedgases emanatingfrom the individual burners Z). These burners are provided with two rowsof holes Z) adapted to direct the flame angularly beneath the sectiontoward the inter-sectional passages formed by the flanges a An air mixerb and a valve I) are respectively associated with each of the burners.Interiorly of each of the vertical water sections are positioned twobattle plates a which. insure the circulation of the water throughoutthe section without unduly impeding its movement. A plurality ofthreaded rods 0, passing through the end plates d, or the lugs c, serveto insure watertight connection between the several vertical sections ofthe heater. The horizontal or top section comprises a reservoir e havingend plates 6'' and threaded nipples e c respectively adapted to connectwith the outlet pipe and with the elbows 9 extending to the uppermanifold or sub-reservoir a'-. The three-sided shell or casing hexteriorly seals the said reservoir, and is provided with an opening 72connected with the chimney stack. A suitable base 2' immediatelymounting the burners and the assembled vertical sections. serves tocomplete the preferred embodiment of the simple water heating appliancemade in accordance with my invention.

I shall now endeavor to point out some of r the advantages attained bymy invention, and explain the manner in which the appli ance operates.Pipe j connecting with the lower manifold or sub-reservoir (1. will beunderstood to extend from the return of the hot water heating system.From this the water is distributed to the several vertical heatingsections, following the general course of the arrows supplied to Fig.II. Under ordinary circumstancesonly a portion of the gas burners willbe'lighted. since. it the 2nd. 4th and 6th burners are lighted. each oneoi? the vertical sections will be adequately and individually heatedthrough the medium of its exposed sides and serpentine flanges. Any oneof these burners. accordingly. will serve to heat three of the adjacentsections, and the full number of burners ordinarily are employed merelyfor quickly starting the hot water into circulation. or because of asudden fall inclosing chamber. from wh h the exhausted gases pass to thechimney through the vent 71.. Accordin ly, the water is provided with arelatively larg' amount of heating surface, and in eonscquemze themaximum temperature for a given fuel consumption is secured. In myimproved heater, moreover, the How of the water impeded butvery little,while by use of the cou'nnunicating manifolds or sub-reservoirs thecirculation is maintained from those sections which re-' move thegreatest amount of heat, as where only a portion of the burners areemployed, while the. hot water is delivered into the common upper reervoir which is positioned in the hottest portion of the, appliance, andfrom which the water circulates immediately through the connected systemof pipingand radiators.

As stated, preferably gaseous fuel, of which natural panels thecheapest, is employed in tiring my innurored heating appli ance, but thesame is not limited thereto. For the reasons stated, it likewise ispreferable to associate a burner with each of the vertical sections, butfrom the foregoing itwill a meat that this is not necessary, since asing e burner is advantageously positioned beneath one section to heatit and the two adjacent Sections as well. lty adopting this sectionalconstruction, it is, of course, apparent that the heating appliance ofmy invention may be readily added to, or partially replaced, ifrequired. flhc' construction, moreover, readily lends itself to theeconomical heating .of large apartments or buildings in small units orsuites, controllable as the individual tenants shall see lit. This isparticularly true of the natural-gas burning heater,.since it is simple,extremely conipact, and may be positioned in an out of the way corner ofthe apartment or the suite which it is desired to heat. I

Having now explained the preferred en1- bodiment of my invention, andindicated its uses and advantages,-I claim as my inven tion, thefollowing 1. In an appliance of the class described, the combinationwith a plurality of vertical sections, each section comprising a centralheating compartment and laterally positioned connecting manifolds, interal flanges provided upon the eiiterior of the hcatin compartments, andindependently eontro lable gas burners respectively positioned adjacentto the lower portions of the severa sections, substantially as setforth. i
